Definitions
- the invention relates to a method for operating a rechargeable battery hand lamp with a lighting source, with a manually operable on / off switch, in particular in the form of a touch switch or button, and control electronics, which detects the instantaneous duty cycle t of the battery hand lamp and the Battery light automatically turns off when the duty cycle t exceeds a predetermined value t 1 . Furthermore, the invention relates to such a battery hand lamp and control electronics for controlling such a battery hand lamp.
- Such methods for operating a rechargeable flashlight are known.
- the rechargeable battery hand lamp simply shuts off when the operating time t is exceeded above the predetermined value t 1 .
- a deep discharge protection is carried out by measuring the discharge end voltage, in that the halogen lamp is automatically switched off when the final discharge voltage is reached and this state is signaled by flashing in a manner not described in detail. Only by manually switching off the headlight is taken out of service.
- the discharge state of a battery of an electrical device is measured to cause an automatic shutdown of an associated consumer, when the battery has been operated for a certain period of time in a certain discharge state. During such a discharge condition, an LED warning light flashes.
- the battery voltage is monitored to practice a deep discharge protection.
- the loads are automatically shut off when a deep discharge threshold is reached. If a minimum charge is reached again, the consumers are automatically switched on again.
- a time-delayed load shut-off is also provided to prevent the consumers from being switched off immediately if the deep discharge threshold is only briefly undershot.
- the status "deep discharge” is indicated by an LED in the energy-saving flashing mode.
- the present invention has for its object to provide a method in which the automatic switching off the battery hand lamp is designed to be more user-friendly.
- This object is achieved according to the invention in that the electric power supplied to the illumination source is lowered by the control electronics at least once for a short time from a nominal power level to a reduced power level compared to the nominal power level and back to the nominal power level is raised.
- the battery flashlight does not turn off surprisingly, but the user is signaled the early shutdown of the battery hand lamp thereby.
- the electrical power is repeatedly, in particular cyclically, lowered and raised again.
- the multiple lowering and re-raising of the electrical power improves the detectability of the signal and reduces the risk that the user confused the signal with a loose contact of the rechargeable battery flashlight.
- the electrical power can be lowered and increased with ever shorter cycles. As the cycles become shorter and shorter, the signal counts down as a countdown, allowing a user to estimate when the battery-powered flashlight will turn off automatically.

- a preferred Process management in which the reduced power level is 30% -95%, in particular 40% -90%, in particular 50% -85% of the nominal power level. This ensures, on the one hand, that the user does not confuse the signal with a malfunction of the battery-powered hand lamp, as would be conceivable, for example, when lowering to a reduced power level of 0 watts.
- the user still has sufficient light to continue his or her activity.
- the time dt during which the electric power is lowered from the nominal power level to the reduced power level and raised back to the nominal power level is preferably 0.5 to 5 seconds, more preferably 0.5 to 3 seconds, more preferably 1 to 2 seconds.

- the predetermined value t 1 after which the rechargeable battery hand lamp automatically switches off, comprises 30 seconds to 30 minutes, in particular 1 minute to 25 minutes, in particular 5 to 20 minutes.
- the method provides that by pressing the on / off switch again during a trigger interval between the first lowering and the automatic switching off at t 1, the instantaneous on-time t of the rechargeable flashlight is reset to 0 seconds or the predetermined value t 1 is increased.
- the control electronics is set to the same state as if the battery-powered hand lamp had just been switched on.
- the predetermined value t 1 can be increased.
- the value t 1 is doubled. In this way it can be prevented that the battery hand lamp off, so the lighting is interrupted, and only by re-pressing the on / off switch, which is preferably designed in the form of a touch switch or button.

Abstract
Description
Die Erfindung betrifft ein Verfahren zum Betreiben einer Akku-Handlampe mit einer Beleuchtungsquelle, mit einem manuell betätigbaren Ein-/Ausschalter, insbesondere in Form eines Berührungsschalters oder -tasters, und einer Steuerelektronik, welche jeweils die momentane Einschaltdauer t der Akku-Handlampe erfasst und die Akku-Handlampe automatisch ausschaltet, wenn die Einschaltdauer t einen vorgegebenen Wert t1 überschreitet. Ferner betrifft die Erfindung eine solche Akku-Handlampe sowie eine Steuerelektronik zum Steuern einer solchen Akku-Handlampe.The invention relates to a method for operating a rechargeable battery hand lamp with a lighting source, with a manually operable on / off switch, in particular in the form of a touch switch or button, and control electronics, which detects the instantaneous duty cycle t of the battery hand lamp and the Battery light automatically turns off when the duty cycle t exceeds a predetermined value t 1 . Furthermore, the invention relates to such a battery hand lamp and control electronics for controlling such a battery hand lamp.
Derartige Verfahren zum Betreiben einer Akku-Handlampe sind bekannt. Um den Akku einer Akku-Handlampe zu schonen, schaltet die Akku-Handlampe beim Überschreiten der Einschaltdauer t über den vorgegebenen Wert t1 einfach ab.Such methods for operating a rechargeable flashlight are known. In order to spare the rechargeable battery of a rechargeable battery hand lamp, the rechargeable battery hand lamp simply shuts off when the operating time t is exceeded above the predetermined value t 1 .
Dies geschieht für den Benutzer meist unvorhersehbar, so dass er durch das automatische Abschalten der Akku-Handlampe überrascht wird und irrtümlich auf ein Durchbrennen der Beleuchtungsquelle schließt.This is usually unpredictable for the user, so that he is surprised by the automatic shutdown of the battery hand lamp and mistakenly concludes a burnout of the illumination source.

Der vorliegenden Erfindung liegt die Aufgabe zugrunde, ein Verfahren vorzuschlagen, bei dem das automatische Ausschalten der Akku-Handlampe benutzerfreundlicher gestaltet ist.The present invention has for its object to provide a method in which the automatic switching off the battery hand lamp is designed to be more user-friendly.
Diese Aufgabe wird erfindungsgemäß dadurch gelöst, dass die der Beleuchtungsquelle zugeführte elektrische Leistung vor dem automatischen Ausschalten der Akku-Handlampe mittels der Steuerelektronik mindestens einmal für eine kurze Zeit dt von einem Nominalleistungsniveau auf ein gegenüber dem Nominalleistungsniveau reduziertes Leistungsniveau abgesenkt wird und wieder zurück auf das Nominalleistungsniveau angehoben wird. Von besonderem Vorteil dabei ist, dass die Akku-Handlampe sich nicht überraschend ausschaltet, sondern dem Benutzer das baldige Abschalten der Akku-Handlampe hierdurch signalisiert wird.This object is achieved according to the invention in that the electric power supplied to the illumination source is lowered by the control electronics at least once for a short time from a nominal power level to a reduced power level compared to the nominal power level and back to the nominal power level is raised. Of particular advantage is that the battery flashlight does not turn off surprisingly, but the user is signaled the early shutdown of the battery hand lamp thereby.
Nach einer vorteilhaften Weiterbildung des erfindungsgemäßen Verfahrens wird die elektrische Leistung mehrfach, insbesondere zyklisch, abgesenkt und wieder angehoben. Durch das mehrfache Absenken und Wiederanheben der elektrischen Leistung wird die Erfassbarkeit des Signals verbessert und die Gefahr reduziert, dass der Benutzer das Signal mit einem Wackelkontakt der Akku-Handlampe verwechselt.According to an advantageous embodiment of the method according to the invention, the electrical power is repeatedly, in particular cyclically, lowered and raised again. The multiple lowering and re-raising of the electrical power improves the detectability of the signal and reduces the risk that the user confused the signal with a loose contact of the rechargeable battery flashlight.
Alternativ hierzu kann die elektrische Leistung mit immer kürzer werdenden Zyklen abgesenkt und wieder angehoben werden. Durch die immer kürzer werdenden Zyklen wird das Signal als Countdown erfasst, wodurch ein Benutzer abschätzen kann, wann die Akku-Handlampe automatisch ausgeschaltet wird.Alternatively, the electrical power can be lowered and increased with ever shorter cycles. As the cycles become shorter and shorter, the signal counts down as a countdown, allowing a user to estimate when the battery-powered flashlight will turn off automatically.
Das reduzierte Leistungsniveau kann zumindest grundsätzlich auch 0 Watt betragen. Bevorzugt wird allerdings eine Verfahrensführung, bei der das reduzierte Leistungsniveau 30 % - 95 %, insbesondere 40 % - 90 %, insbesondere 50 % - 85 % des Nominalleistungsniveaus beträgt. Dadurch wird zum einen gewährleistet, dass der Benutzer das Signal nicht mit einer Störung der Akku-Handlampe verwechselt, wie es beispielsweise bei einem Absenken auf ein reduziertes Leistungsniveau von 0 Watt denkbar wäre. Darüber hinaus steht dem Benutzer bei einem reduzierten Leistungsniveau von 30% - 95 % des Nominalleistungsniveaus noch ausreichend Licht zum Fortführen seiner Tätigkeit zur Verfügung.The reduced power level can be at least 0 watts, at least in principle. However, a preferred Process management in which the reduced power level is 30% -95%, in particular 40% -90%, in particular 50% -85% of the nominal power level. This ensures, on the one hand, that the user does not confuse the signal with a malfunction of the battery-powered hand lamp, as would be conceivable, for example, when lowering to a reduced power level of 0 watts. In addition, at a reduced power level of 30% -95% of the nominal power level, the user still has sufficient light to continue his or her activity.
Die Zeit dt, während der die elektrische Leistung von dem Nominalleistungsniveau auf das reduzierte Leistungsniveau abgesenkt wird und wieder zurück auf das Nominalleistungsniveau angehoben wird, beträgt vorzugsweise 0,5 - 5 Sekunden, insbesondere 0,5 - 3 Sekunden, insbesondere 1 - 2 Sekunden. Die Zeit dt umfasst die Zeitspanne ab Unterschreiten der elektrischen Leistung unter das Nominalleistungsniveau bis zu dem Zeitpunkt, an dem die elektrische Leistung wieder das Nominalleistungsniveau erreicht. Die Phasen des Absenkens der elektrischen Leistung auf das reduzierte Leistungsniveau und Wiederanhebens auf das Nominalleistungsniveau sind in der Zeit dt mit inbegriffen. Dadurch, dass die Zeit dt 0,5 - 5 Sekunden beträgt, ist das Signal für dem Benutzer als solches einfacher erfassbar und von einer technischen Störung leichter unterscheidbar.The time dt during which the electric power is lowered from the nominal power level to the reduced power level and raised back to the nominal power level is preferably 0.5 to 5 seconds, more preferably 0.5 to 3 seconds, more preferably 1 to 2 seconds. The time dt includes the period of time from when the electric power falls below the nominal power level until the time when the electric power reaches the nominal power level again. The phases of lowering the electrical power to the reduced power level and raising it back to the nominal power level are included in the time dt. As a result of the time dt being 0.5-5 seconds, the signal is easier to detect for the user as such and more easily distinguishable from a technical fault.
Es hat sich als vorteilhaft erwiesen, wenn der vorgegebene Wert t1, nach dessen Überschreiten die Akku-Handlampe automatisch ausschaltet, 30 Sekunden bis 30 Minuten, insbesondere 1 Minute - 25 Minuten, insbesondere 5 - 20 Minuten umfasst.It has proved to be advantageous if the predetermined value t 1 , after which the rechargeable battery hand lamp automatically switches off, comprises 30 seconds to 30 minutes, in particular 1 minute to 25 minutes, in particular 5 to 20 minutes.
Ferner wird eine Weiterbildung des Verfahrens vorgeschlagen, bei dem die der Beleuchtungsquelle zugeführte elektrische Leistung 10 Sekunden - 3 Minuten, insbesondere 10 Sekunden - 2 Minuten, insbesondere 20 Sekunden - 1 Minute vor dem automatischen Ausschalten abgesenkt wird.Furthermore, a further development of the method is proposed in which the electric power supplied to the illumination source is lowered for 10 seconds-3 minutes, in particular 10 seconds-2 minutes, in particular 20 seconds-1 minute before the automatic switch-off.
Schließlich sieht eine Weiterbildung des Verfahrens vor, dass durch erneutes Betätigen des Ein-/Ausschalters während eines Triggerintervalls zwischen dem erstmaligen Absenken und dem automatischen Ausschalten bei t1 die momentane Einschaltdauer t der Akku-Handlampe auf 0 Sekunden zurückgesetzt wird oder der vorgegebene Wert t1 erhöht wird. Durch das Zurücksetzen der Einschaltdauer t auf 0 Sekunden ist die Steuerelektronik in den gleichen Zustand gesetzt, als wäre die Akku-Handlampe gerade erst eingeschaltet worden. Alternativ dazu kann der vorgegebenen Werts t1 erhöht werden. Bevorzugt wird der Wert t1 verdoppelt. Auf diese Weise kann verhindert werden, dass die Akku-Handlampe ausschaltet, also die Beleuchtung unterbrochen wird, und zwar lediglich durch erneutes Betätigen des Ein-/Ausschalters, der vorzugsweise in Form eines Berührungsschalters oder -tasters ausgebildet ist.Finally, a further development of the method provides that by pressing the on / off switch again during a trigger interval between the first lowering and the automatic switching off at t 1, the instantaneous on-time t of the rechargeable flashlight is reset to 0 seconds or the predetermined value t 1 is increased. By resetting the duty cycle t to 0 seconds, the control electronics is set to the same state as if the battery-powered hand lamp had just been switched on. Alternatively, the predetermined value t 1 can be increased. Preferably, the value t 1 is doubled. In this way it can be prevented that the battery hand lamp off, so the lighting is interrupted, and only by re-pressing the on / off switch, which is preferably designed in the form of a touch switch or button.
Zur Lösung genannter Aufgabe wird ferner eine Akku-Handlampe vorgeschlagen, bei der die Steuerelektronik so ausgebildet ist, dass die der Beleuchtungsquelle zugeführte elektrische Leistung vor dem automatischen Ausschalten der Akku-Handlampe mindestens einmal für eine kurze Zeit dt von einem Nominalleistungsniveau auf ein gegenüber dem Nominalleistungsniveau reduziertes Leistungsniveau abgesenkt wird und wieder zurück auf das Nominalleistungsniveau angehoben wird.To solve the above object, a battery hand lamp is further proposed in which the control electronics is designed so that the illumination source supplied electrical power before automatically switching off the battery flashlight at least once for a short time dt from a nominal power level to one compared to the nominal power level Reduced level of performance is lowered and raised back to the nominal level of performance.

Es erweist sich weiter als vorteilhaft, wenn die Steuerelektronik so ausgebildet ist, dass das reduzierte Leistungsniveau 30 % - 95 %, insbesondere 40 % - 90 %, insbesondere 50 % - 85 % des Nominalleistungsniveaus entspricht.It also proves to be advantageous if the control electronics are designed such that the reduced power level corresponds to 30% -95%, in particular 40% -90%, in particular 50% -85%, of the nominal power level.
Ferner wird eine Ausführungsform bevorzugt, bei der die Steuerelektronik so ausgebildet ist, dass die Zeit dt, während der die elektrische Leistung von dem Nominalleistungsniveau auf das reduzierte Leistungsniveau abgesenkt wird und wieder zurück auf das Nominalleistungsniveau angehoben wird, 0,5 - 5 Sekunden, insbesondere 0,5 - 3 Sekunden, insbesondere 1 - 2 Sekunden umfasst.Further, an embodiment is preferred in which the control electronics are arranged such that the time dt, during which the electric power is lowered from the nominal power level to the reduced power level and raised back to the nominal power level, 0.5 - 5 seconds, in particular 0.5 - 3 seconds, especially 1 - 2 seconds.
Ferner erweist es sich als vorteilhaft, wenn der vorgegebene Wert t1, nach dessen Überschreiten die Akku-Handlampe automatisch ausschaltet, 30 Sekunden - 30 Minuten, insbesondere 1 - 30 Minuten, insbesondere 5 - 20 Minuten beträgt.Furthermore, it proves to be advantageous if the predetermined value t 1 , after which the battery flashlight automatically switches off, is 30 seconds - 30 minutes, in particular 1 - 30 minutes, in particular 5 - 20 minutes.

Schließlich wird eine Ausführungsform der Akku-Handlampe bevorzugt, bei der die Steuerelektronik so ausgebildet ist, dass durch erneutes Betätigen des Ein-/Ausschalters während des Triggerintervalls zwischen dem erstmaligen Absenken und dem automatischen Ausschalten bei t1 die momentane Einschaltdauer t der Akku-Handlampe auf 0 Sekunden zurückgesetzt wird oder der vorgegebene Wert t1 erhöht wird.Finally, an embodiment of the rechargeable flashlight is preferred in which the control electronics are designed such that that by pressing the on / off switch again during the trigger interval between the first lowering and the automatic switching off at t 1, the instantaneous duty cycle t of the rechargeable battery flashlight is reset to 0 seconds or the predetermined value t 1 is increased.
